Presentation

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

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

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