Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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