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