I removed the remove the /Users/hectorbanos/.sage/temp/ directory but the error still stands. What else I can do?. By the way thanks for the help

I tried your example and it worked, but I don't know why mine does not work.

Hi Im using 6.3 A couple of week ago it used to work.

For example

 sage: cube = PermutationGroup(["(3,2,6,7)(4,1,5,8)","(1,2,6,5)(4,3,7,8)", "(1,2,3,4)(5,6,7,8)"])
sage: cube
Permutation Group with generators [(1,2,3,4)(5,6,7,8), (1,2,6,5)(3,7,8,4), (1,5,8,4)(2,6,7,3)]
sage: cube.cardinality()
Traceback (most recent call last):
...
TypeError: Gap terminated unexpectedly while reading in a large line:

I have acode that use to run very good, but I dont know why no longer the basic functions works for my permutation groups, i.e Abelian, cardinality, order. Only degree seems to work
