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