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