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