✦ Synopsis

The countable spaces whose product with the sequential fan S, have countable tightness are characterized.

As a consequence. it is shown that if ?l x S, has countable tightness then X has countable fan-tightness.

We present three examples of countable spaces with a single nonisolated point. The first gives, assuming CH, a FrCchet-Urysohn tight point which does not have countable absolute tightness; the second, constructed with the help of o, gives a tight non-weakly Frkchet-Urysohn point without countable ab
