[GAP Forum] Replacing in GAP

[AHMET ARIKAN]

Dear All, one of my colleagues asked me the following question which seems 
easy but useful:

Let  y=(a_1,a_2,...,a_k) be a cycle of length k where a_i is a natural 
number for each i. Is there a way in GAP to replace some determined 
components with some other natural numbers (for example replace a_{i_1},..., 
a_{i_t} with some different natural numbers). Of course it can be done 
manually, but it is not helpful for him.

With best wishes,

Ahmet Arikan
