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