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