How to remove an account the is our of order?

SUGGESTED

I have removed/reversed the transactions in the account.  But I still can't delete it.  The number of the account fall directly inbetween another 2 accounts that are in use.  so I can't create a new header account to delete this one.  It is stuck our in no mans land.  And I cant change the acct number to make it fall "in line"  Because it is out of order I cannot view any of my income or balance statements.  there must be a way to remove this errant account.  Any ideas?
