Presentation

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

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

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