Of the sequences of type a(n)=A095904(a(n-1)-1), this one has an exceptionally high number of terms under 1000. It is unknown if this sequence continues indefinitely in both directions, is part of a loop, or is part of the sequence A179223. %H A179224 Will Nicholes, <a href="http://willnicholes.com/math/primesigmap.htm">Iterative mapping of prime signatures</a>. %Y A179224 Cf.
