Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 56th year, we are closing in on 350,000 sequences, and we’ve crossed 9,700 citations (which often say “discovered thanks to the OEIS”).

 OFFSET 0,1 COMMENTS Number of straight line segments (chisel strokes) in the capitalized English name of n (excluding spaces and hyphens), counting smooth curves as zero strokes. The 15 letters which are entirely strokes (no curves): A(3), E(4), F(3), H(3), I(1), K(3), L(2), M(4), N(3), T(2), V(2), W(4), X(2), Y(3), Z(3). Those 4 which are entirely curves (and count as zero): C, O, S, U. Those 7 which mix strokes and curves: B(1), D(1), G(2), J(1), P(1), Q(1), R(2). a(16)=16 is a fixed point. The numbers written entirely from stroke-only letters are A163670. LINKS EXAMPLE a(0) = 9 because ZERO has (letter by letter) 3+4+2+0 = 9 straight line segments (chisel strokes). a(1) = 7 because ONE has 0+3+4 = 7 strokes. a(20) = 18 because TWENTY (all strokes) has 2+4+4+3+2+3 = 18 strokes.
