Presentation

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

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

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