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