This diagram depicts the first 9 marks:
\ / \ / \ /
--4---5---.--
/ \ / \ / \
-7---1---2---8-
\ / \ / \ / \
--6---3---9--

a(1) = number of steps between 1st and 2nd marks = 1;
a(2) = number of steps between 2nd and 3rd marks = 1;
a(3) = number of steps between 3rd and 4th marks = 2;
a(4) = number of steps between 4th and 5th marks = 1;
a(5) = number of steps between 5th and 6th marks = 2;
a(6) = number of steps between 6th and 7th marks = 1;
a(7) = number of steps between 7th and 8th marks = 3;
a(8) = number of steps between 8th and 9th marks = 1.
