ATLAS: Suzuki group Suz
Order = 448345497600 = 2^{13}.3^{7}.5^{2}.7.11.13.
Mult = 6.
Out = 2.
The following information is available for Suz:
Standard generators of the Suzuki group Suz are a
and b where a is in class 2B, b is in class 3B,
ab has order 13 and ababb has order 15.
Standard generators of 2.Suz are preimages A and B where
B has order 3 and AB has order 13.
Standard generators of 3.Suz are preimages A and B where
A has order 2 and AB has order 13.
Standard generators of 6.Suz are preimages A and B where
A has order 4, B has order 3 and AB has order 13.
Standard generators of the automorphism group Suz:2 are c
and d where c is in class 2C,
d is in class 3B and cd has order 28.
Standard generators of 2.Suz:2 are preimages C
and D where D has order 3.
Standard generators of 3.Suz:2 are preimages C and D where
D is in class +3B (equivalently, CDCDD has order 7).
Standard generators of 6.Suz:2 are preimages C and D where
D has order 3 and CDCDD has order 7 or 14.
(The order of CDCDD is determined by the sixfold cover.)
The outer automorphism of Suz may be realised by mapping
a, b to
a^{abab}, b^{abbabb}.
If c' is the 15th power of this automorphism, and d' = b,
then (c', d') is conjugate to (c, d).
Another outer automorphism [with shorter words] maps a, b to
a, b^{ababbab}.
If u is this second automorphism, then u is class 8H and
((babu)^{7}, b^{aba}) is conjugate to (c, d).
Finding generators
To find standard generators for Suz:
 Find any element of order 14. Its 7th power is a 2Belement, x say.
[The probability of success at each attempt is 1 in 28.]
 Find any element of order 9 or 18. This powers up to a 3Belement, y say.
[The probability of success at each attempt is 4 in 27 (about 1 in 7).]
 Find a conjugate a of x and a conjugate b of
y such that ab has order 13 and ababb has order 15.
[The probability of success at each attempt is 18 in 715 (about 1 in 40).]
This algorithm is available in computer readable format:
finder for Suz.
To find standard generators for Suz.2:
 Find any element of order 30. It powers up to a 2Celement, x say.
[The probability of success at each attempt is 1 in 30.]
 Find any element of order 9 or 18. This powers up to a 3Belement, y say.
[The probability of success at each attempt is 2 in 27 (about 1 in 14).]
 Find a conjugate c of x and a conjugate d of y whose product has order 28.
[The probability of success at each attempt is 27 in 143 (about 1 in 5).]
This algorithm is available in computer readable format:
finder for Suz.2.
Checking generators
To check that elements x and y of Suz
are standard generators:
 Check o(x) = 2
 Check o(y) = 3
 Check o(xy) = 13
 Check o(xyxyy) = 15
 Check o(xyxyxyy) = 12
This algorithm is available in computer readable format:
checker for Suz.
To check that elements x and y of Suz.2
are standard generators:
 Check o(x) = 2
 Check o(y) = 3
 Check o(xy) = 28
 Check o(xyxyxyyxyy) = 7
This algorithm is available in computer readable format:

A set of generators for the maximal cyclic subgroups can be obtained
by running this program on the standard
generators. All conjugacy classes can therefore be obtained as suitable
powers of these elements.
Problems of algebraic conjugacy are not yet dealt with.
