Presentation

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

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

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