Place the numbers 1 to 12 in the 12 locations on the sixpointed star,
such that each of the six lines of four numbers has the same sum and
the sum of the
six points of the star has the same sum as the lines.

Can you find an arrangement for which the six lines and the set of
six starpoints produce seven consecutive sums?
