Presentation

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

A minimal faithful permutation representation — 3 generators on 28 points:

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