COMMENTS

Same as Pisot sequences E(1, 29), L(1, 29), P(1, 29), T(1, 29). Essentially same as Pisot sequences E(29, 841), L(29, 841), P(29, 841), T(29, 841). See A008776 for definitions of Pisot sequences.
The compositions of n in which each natural number is colored by one of p different colors are called pcolored compositions of n. For n>=1, a(n) equals the number of 29colored compositions of n such that no adjacent parts have the same color.  Milan Janjic, Nov 17 2011
Numbers n such that sigma(29*n) = 29*n + sigma(n).  Jahangeer Kholdi, Nov 23 2013
