Presentation

minimal degreeμ(G) = 23
transitive degreeμt(G) = 112

A minimal faithful permutation representation — 2 generators on 23 points:

(1,2,4,6,7,5,3)(8,9,12,15)(10,17,19,23)(11,20,18,14)(13,21,22,16);(2,3)(4,5)(6,7)(9,13)(10,16)(11,18)(14,23)(15,22)(17,20)(19,21)

Polycyclic presentation:

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