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