[Not linked to yet: this page is still being prepared.]
- U6(2) and covers
-
Standard generators of U6(2) are a and b where
a is in class 2A, b has order 7, ab has order 11 and
abb has order 18.
Standard generators of the double cover 2.U6(2) are preimages
A and B where B has order 7, AB has order 11
and ABBB has order 11.
Standard generators of the triple cover 3.U6(2) are preimages
A and B where A has order 2 and B has order 7.
Standard generators of the sixfold cover 6.U6(2) are preimages
A and B where A has order 2, B has order 7,
AB has order 33 and ABBB has order 11.
Standard generators of 22.U6(2) are preimages A
and B where B has order 7 and AB has order 11.
Standard generators of (22 × 3).U6(2) are
preimages A and B where A has order 2, B has
order 7 and AB has order 33.
- U6(2):2 and covers
-
Standard generators of U6(2):2 are c and d where
c is in class 2D, d is in class 6J and cd has order 11.
Standard generators of either double cover 2.U6(2).2 are preimages
C and D where CD has order 11.
Standard generators of the triple cover 3.U6(2):2 are preimages
C and D where CD has order 11.
Standard generators of either sixfold cover 6.U6(2).2 are preimages
C and D where CD has order 11.
Standard generators of 22.U6(2):2 are preimages
C and D where C has order 2, D has order 6
and CDCDCDCDCDDCDCDDCDDCDD has order 7.
- U6(2):3 and covers
-
Standard generators of U6(2):3 are e and f where
e is in class 3D, f has order 11, ef has order 21
and eff has order 18.
Standard generators of 3.U6(2):3 are preimages E and
F where F has order 11.
Standard generators of 22.U6(2):3 are preimages
E and F where F has order 11.
- U6(2):S3 and covers
-
Standard generators of U6(2):S3 are g and
h where g is in class 2D, h is in class 6J [6J'/6J''
from the point of view of U6(2)] and gh has order 21.
Standard generators of 3.U6(2):S3 are preimages
G and H. No extra conditions are required, as all such pairs
are automorphic.
Standard generators of 22.U6(2):S3 are
preimages G and H where ...
An automorphism of U6(2) of order 3 can be obtained by mapping
(a, b) to
((abb)^-4a(abb)^4,
(abababbab)^-1babababbab).
An automorphism of U6(2) of order 2 can be obtained by mapping
(a, b) to
(a, b^-1).
This automorphism normalises the double cover defined by the standard
generators, but interchanges the other two double covers.
< a, b | a2 = b7 =
(ab)11 = [a, b]2 =
[a, b2]3 =
[a, b3]3 =
(ab3)11 =
(abab2ab3ab-3)7
= 1 >.
The last two relations are just quotienting out central involutions from a
group of shape 22.U6(2).
