Presentation

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

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

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