review text: Die Euler'schen ''numeri idonei'' sind jene natürlichen Zahlen m, für welche die Kompositionsklassengruppe binärer Formen der Diskriminante - 4m nur eine Klasse im Geschlecht hat; es wird über die wichtigsten Resultate von L. Euler, C. F. Gauss and \textit{F. Grube} [Über einige Euler'sche Sätze aus der Theorie der quadratischen Formen, Z. Math. Phys. 19, 492-519 (1874)] referiert.
