Dear SeqFan readers,

My name is Floor van Lamoen, and I am a newby on this list. I was asked
to tell something about myself and my interests.
I am a high school mathematics teacher from Goes, the Netherlands, and
in fact my main interest in mathematics is in (classical Euclidean)
geometry. But I also like integer sequences, be it on more recreational
level. To show that these interests can be combined sometimes, below are
two sequences that I submitted today.

Best regards,
Floor van Lamoen.
