Presentation

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

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

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