| Jun 10 at 11:25 | comment | added | scsnm | OK. Thanks. Do you mean the Inndiag is wrong or the centralizers? | |
| Jun 10 at 11:08 | comment | added | Dave Benson | I suspect that you have the wrong group. If G is the simple group then the multiplier of $G$ is $2\times 2$ while the outer automorphism group is $S_4$. The outer automorphisms act on the $2\times 2$ through the quotient $S_3$. So any particular double cover of $G$ has fewer automorphisms than $G$. And even the double covers that admit involutary automorphisms don't necessarily fit together to make a group of the form $2.G.2$. So my suspicion is that the group is twice as big as you think, but without a lot of work trying to reconcile your notation with GLS, it's hard to comment further. | |

| Jun 9 at 22:50 | comment | added | scsnm | OK. I will post them. | |
| Jun 9 at 22:45 | comment | added | LSpice | Re, yes, if you have specific expected results and actual results, then it would probably help to post them. | |
| Jun 9 at 22:22 | comment | added | scsnm | Yes, yes. Do you mean the computation results? thank you | |
| Jun 9 at 13:58 | comment | added | LSpice | It seems hard to answer the question without knowing your results. Could you summarise them? | |
