Presentation

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

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

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