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