Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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