Many thanks!
We have another examples WITHOUT capital E but unfortunately they are
random and so it is very hard to repeat them. We don't think that can be!
Thanks once more!

You may want to look out for variables called 'Z' - this is used by GAP to
access finite field elements, so overwriting it will cause problems
similar to 'E'. Moreover, there are some variables consisting of two
capital letters. (According to GAP conventions, your variables should
never start with a capital letter, these are reserved by the library.)
