Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 5 generators on 28 points:

(2,4)(5,6)(7,11)(8,12)(9,10)(13,14)(15,20)(16,18)(17,19)(21,22,25,26)(23,24,27,28);(6,9)(11,12)(14,16)(17,20)(22,26)(23,27);(5,7,10,8)(6,11,9,12)(13,15)(14,17)(16,20)(18,19)(21,23)(22,24)(25,27)(26,28);(1,2)(3,4)(5,8,10,7)(6,12,9,11)(13,16,18,14)(15,20,19,17)(21,24)(22,23)(25,28)(26,27);(5,9,10,6)(7,12,8,11)(13,17,18,20)(14,19,16,15)(21,22)(23,24)(25,26)(27,28)
