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