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