Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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