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