Resumen de Aritmética de las sucesiones 6n-1,6n+1 y de los primos gemelos
This paper considers questions equivalent and similar to those of twin numbers. Two prime numbers are said to be twin if they differ in two units. Except for the pair (3,5), they may be expressed as ($6n-1,6n+1$). The set of the multiples of 6 which separate twin numbers is studied. A theorem of relative density is included ($\S$ 10) as ewll an inductiv process of functional generation of the prime numbers ($\S$ 11).
