Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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

Polycyclic presentation:
