Presentation

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

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

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