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