Resumen
- Let $(x_n)$ be a strong $M$-basis of a Banach space, then:\newline in general the block sequences of $(x_n)$ are not strong $M$-basic, also if $(x_n)$ is uniformly minimal; moreover, if all the block sequences of $(x_n)$ are strong $M-$basic, in general $(x_n)$ is neither uniformly minimal nor basic with brackets.
