Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 3 generators on 28 points:

(2,4)(5,6,10,7)(8,12,9,11)(13,14,17,21,18,20,16,26)(15,22,25,27,23,28,24,19);(1,2,3,4)(5,7,8,12,10,6,9,11)(13,15,16,24,18,23,17,25)(14,19,21,22,20,27,26,28);(5,6,10,7)(8,12,9,11)(14,20)(15,23)(16,17)(22,28)

Polycyclic presentation:
