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

Polycyclic presentation:

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