Presentation

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

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

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