Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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