Presentation

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

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

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