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