Applications of the evaluated determinants can be found in [arXiv:math.NT/0509523]. Note that the two determinants are actually special cases of Theorems 20 and 23 in [arXiv:math.CO/9902004], respectively. Since this paper does not provide any new results, it will not be published anywhere.9 pagesNumber TheoryCombinatorics15A36; 15A15; 11C20; 11A07text
