Passage: The "H" stands for Otto Hölder, who first proved in 1882 what mathematicians now think of as the connection between Abel summation and (H, n) summation; 1 − 2 + 3 − 4 +... was his first example. Kasunyatan bilih 1⁄4 inggih punika (H, 2) gunggung saking 1 − 2 + 3 − 4 +... njamin bilih punika inggih punika gunggung Abel ugi; punika ugi badhé dipunbuktiaken langsung ing ngandhap.  Pitakonan: Kapan Otto mbuktèkaké apa-apa ing babagan matématika?
