Hi again,
Note also that GAP handles permutations identically to SymPy, and the
manual states unambiguously that "GAP multiplies permutations from left to
right!":

Hi Chris,
The convention that I'm familiar with is that the notation (both cycle
notation and the two-line notation) represents the exchange of *elements*,
not positions. See for example

pp. 4--5.
So my interpretat
Hi Chris,
Thanks for your response. When you write,
> If you let `p = Permutation(1,2)(2,3)` then `p.list()` gives `[0, 3, 1,
2]` which is consistent with R to L interpretation
I think this is incorrect (and I contend that the docs are incorrect on
this point as well).
Multiplying the transposi
Hi everyone,
I've been experimenting with the "Permutations" module, trying to follow
the examples in the documentation here:
https://docs.sympy.org/latest/modules/combinatorics/permutations.html
As expected,
Permutation(1, 2)(2, 3) == Permutation(1, 2) * Permutation(2, 3)
But doesn't this me
