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