Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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