%N a(n) is the largest highly composite number (definition 1) not a multiple of n.

%C In other words, largest element of A002182 not a multiple of n.

%C For all m there exists a k such that A002182(k+i) is divisible by m for all i >= 0, so the sequence is well-defined.

%Y Cf. A002182, A022404.

%K nonn

%O 2,2
