#Example: "B2-4-Id" . . . alternative way to generate B(2, 4) #Generates B(2, 4) by using the `Identities' option #... this is not as efficient as using `Exponent' but #demonstrates the usage of the `Identities' option. #vars: F, f, procId; #options:
F := FreeGroup("a", "b"); ## All words w in the pc generators of B(2, 4) satisfy f(w) = 1
f := w -> w^4; #alt: do #procId := PqStart( F ); #alt: sub <procId> for <F>
Pq( F : Prime := 2, Identities := [ f ] );
