We give a non-trivial upper bound for F h ðg; NÞ, the size of a B h ½g subset of f1; . . . ; Ng, when g > 1. In particular, we prove F 2 ðg; NÞ41:864ðgNÞ 1=2 þ 1, and F h ðg; NÞ4 1 ð1þcos h ðp=hÞÞ 1=h ðhh!gNÞ 1=h , h > 2. On the other hand, we exhibit B 2 ½g subsets of f1; . . .

## Abstract Verification of the computation of local quantities of interest, e.g. the displacements at a point, the stresses in a local area and the stress intensity factors at crack tips, plays an important role in improving the structural design for safety. In this paper, the smoothed finite elem
