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