... explained in more detail in Casselman (1994). There is an important difference, however: in the earlier routine, floating point numbers were used to check an inequality involving real roots, in order ... sophisticated programming. In addition to the practical interest in exploring Coxeter groups compu- tationally, there are mathematical problems interesting in their own right in...

... conditions: • inv ij +inv jk =inv ij (+1) for i<j<k; • inv ij +inv ki =inv kj (+1) for i<j≤k; • inv ik +inv ji =inv kj (+1) for i ≤ j ≤ k and i<k; • inv jk +inv ji =inv ki (+1) for ... position zero, giving δ ≥ n+1 (and using s 0 once), while positive numbers will stop to the right of position zero, giving δ ≤ n (and not using s 0 ). Since the permutation is increasing in the se...

... square-counting or an interlacing argument, one can show that the max- imum number of vertices in an independent set in the Hoffman-Singleton graph is 15. If S is an independent set of size 15 in this ... Then H is the Hoffman-Singleton graph. Note that we may view the vertices in S as points and the vertices not in S as lines, with a point and line incident if the corresponding verti...

... the cosets of T. Since the intersection of any line with any equivalence class contains at most one point, x=1, we see that t can only fix two points on any line, since the fixed points are all in one equivalence ... the points on the line joining the two points. Hence, either the fixed points of H are just the points of the line l or the conclusions of the lemma hold. If the fixed point set is...
