Presentation

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

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

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