[GAP Forum] help with polycyclic

[Ayan Mahalanobis]

Hello,
I am new in GAP and was trying to come up with a polycyclic presentation 
of a 2-group. I couldn't get it to work.
The message I am getting is this

gap>UpdatePolycyclicCollector(flt);
gap> IsConfluent(flt);
Inconsistency at 4 3 2
false

The message makes no sense to me. I can provide with more details 
including the Fp definition of the group, if necessary.

Thanks and regards
Ayan
