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