Order Functions

Unless the order is already known, each of the functions in this family will create the class image of the automorphism group to compute the order.

Order(A) : GrpAuto -> RngIntElt

# A : GrpAuto -> RngIntElt

The order of the group A, returned as an integer. If this is not already known it will be calculated by a call to the ClassImage function.

FactoredOrder(A) : GrpAuto -> [ <RngIntElt, RngIntElt> ]

The factored order of the group A. If this is not already known it will be calculated by a call to the ClassImage function.

OuterOrder(A) : GrpAuto -> RngIntElt

The order of the outer automorphism group associated with A.
