%N Numbers n such that A118799(n) = 0.

%F n such that the following matrix is singular:

%F |prime(n) prime(n+1) prime(n+2) prime(n+3) |

%F |prime(n+4) prime(n+5) prime(n+6) prime(n+7) |

%F |prime(n+8) prime(n+9) prime(n+10) prime(n+11)|

%F |prime(n+12) prime(n+13) prime(n+14) prime(n+15)|

%e a(1) = 21 because A118799(21) = 0 because of the singular matrix:

%e | 73 79 83 89|

%e | 97 101 103 107|

%e |109 113 127 131|

%e |137 139 149 151|.

%e a(4) = 80 because A118799(80) = 0 because of the singular matrix:

%e |409 419 421 431|

%e |433 439 443 449|

%e |457 461 463 467|
