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