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