Presentation

minimal degreeμ(G) = 15
transitive degreeμt(G) = 56

A minimal faithful permutation representation — 2 generators on 15 points:

(1,2,4,6,7,5,3)(8,10)(9,12)(11,14)(13,15);(2,3)(4,5)(6,7)(8,9,11,13,12,10,15,14)

Polycyclic presentation:

2^5,7|a^2=c,c^2=e,d^2=e,b^a=bd,d^a=de,f^a=f^6,d^b=de
