… We continue with the details of the one-loop calculation. It should be kept in mind that we
will only compare the Wilson, Liischer-Weisz and square actions, and therefore we set to
zero all tree-level coefficients except co, cl and ca, and all one-loop coefficients except c~, c~,
c~ and c~. … In this paper we computed Lambda ratios, one-loop Symanzik coefficients and
the tadpole parameter for the Liischer-Weisz and square actions. The results are
summarized in Table 5. We remind the reader that …

We compute the one-loop coefficients for an alternative Symanzik-improved pure gauge SU(N) lattice action (N = 2 and N = 3). For the standard Symanzik-improved action we confirm previous results by Lüscher and Weisz.
