Weyl anomaly of conformal higher spins on six-sphere

This paper is a sequel to (arXiv:1309.0785) were we computed the Weyl anomaly a (Euler density or logarithmic divergence on Sd) coefficient for higher-derivative conformal higher spin field in d=4 and shown that it matches the expression found in (arXiv:1306.5242) by a "holographic" method from a ratio of massless higher spin determinants in AdS5. Here we repeat the same computation in on 6-sphere and demonstrate that the result matches again the one following from AdS7. We also discuss explicitly similar matching in the d=2 case
