Presentation

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

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

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